Knowledge Areas of Related Disciplines 1. Software Requirements This Knowledge Area is concerned with defining the constraints a piece software of software will have, generally involving practical problems, rather than theoretical ones. The Software Requirements KA describes the process, elicitation, analysis, specification, validation, and considerations to be made regarding the software requirements. In addition, this KA defines different types of requirements, such as functional and nonfunctional requirements, emergent properties, quantifiable requirements, and system requirements. Furthermore, there are built-in standards for reassessing and updating the processes the knowledge area defines. 2. Software Design This Knowledge Area is concerned with the design of software. That is, breaking a software system in to appropriate pieces to better facilitate the development of the software system. To that end, the Software Design Knowledge Area describes different design patterns, quality analysis, notations and strategies for designing software. This knowledge area defines ideas such as abstraction, coupling and cohesion, decompostion and modularization, and encapsulation. This knowledge area also describes different notations, such as Entity-relationship diagrams and Component diagrams. It goes on to describe design strategies, such as structured and object-oriented design. 3. Software Construction This Knowledge Area describes the actual implementation of the software system, in accordance to the requirements and design. However, this is more than just programming, but includes some debugging and testing. Large parts of this knowledge area are dedicated to constructing software in such a way that the task naturally makes itself easier and more fault-resistent. This is where topics such as standards conformance, unit tests are of incredible use and importance. This KA also describes what I consider good basic programming skills, namely minimizing complexity and code reuse. To me, these parts of the knowledge area seem reminiscent of the UNIX Philosophy, where you make one piece of code do one simple thing well, and build up complexity by combining smaller pieces of code. 4. Software Testing This knowledge area describes testing, as well as techniques and processes for testing software systems. The Software Testing Knowledge Area is stresses the fact that tests must be carefully selected, so that a relatively small number of tests have a significant impact and meaningful results. Testing also explicitly happens by actually executing code. This KA describes different goals of testing, such as requirements testing and correctness testing, where the software is tested to see if it meets the customers requirements and behaves correctly, respectively. Also described is stress testing, the process of seeing how the software performs under very high load. This will have direct application to our project. Additionally, a large number of techniques for testing are described, including fault- based techniques and usage-based techniques. 5. Software Maintenance This knowledge area describes software maintenance, its processes and techniques. This includes planning for maintenance prior to release, as well as fixing problems and providing support after release. Maintenance includes reevaluating the software to make sure it still meets requirements, or indeed whether or not those requirements need updating later in the software’s life cycle. Part of this knowledge area is concerned with the categorization of different types of maintenance, with four main categories (preventive, perfective, corrective, and adaptive). Also discussed are the cost implications of continued maintenance, and the cycle of the software maintenance process. 6. Software Configuration Management This Knowledge Area describes standards for the management of the various properties of the different elements of the system. This includes the process by which changes to the software are requested, evaluated, approved and implemented. The Software Configuration Management Knowledge Area also describes the tracking of software status, and the processes by which software is built and released, including documentation and release notes. To me, the most interesting thing out of this knowledge area is the explicitly labeled difference between versions, revisions, and variants. It makes sense why that would be standardized, but in my experience, these terms are often used interchangeably, which I don’t consider to be a good thing. 7. Software Engineering Management This Knowledge Area defines items concerning Software Engineering Management, considering any special characteristics software engineering projects have compared to general engineering projects, namely the rapidly changing nature of technology - and therefore the rapidly changing nature of requirements - coupled with the often underappreciated complexity of software engineering. The Software Engineering Management Knowledge Area describes concepts in software project planning, enactment, and evaluation. Together, much of this sounds very similar to what we have done in following RUP for class. 8. Software Engineering Process This Knowledge Area defines “software engineering process” in three different ways, though only focuses on one. ● The process used to engineer software ● processes related to software engineering ● set of activities performed within an organization The Software Engineering Process Knowledge area defines ideas relating to software life cycles, and process assessment, among others. 9. Software Engineering Tools and Methods This Knowledge Area defines terms related to the tools and methods of software engineering. The tools are usually computer- based, and provide some automation of the software engineer’s task. These tools aid in reducing human error by removing the burden of repetitive tasks. The Software Engineering Tools and Methods Knowledge Area defines several categories for tools: Requirements, Design, Construction, Testing, Maintenance, Configuration Management, Engineering Management, Engineering Process, and Quality. These reflect the other Knowledge Areas that compose SWEBOK. This Knowledge Area also defines different methods the tools and engineers can use to go about their task. 10. Software Quality The Sofware Quality Knowledge Area describes ways of achieving software quality, through both static and dynamic techniques. This knowledge area defines concepts concerning quality assurance, verification and validation, reviews and audits, as well as practical measures that can be taken to ensure a software’s quality meets the client’s expectations. Like many other KAs, this KA defines a Management process by which software engineers can systematically achieve high software quality. 11. Knowledge Areas of Related Disciplines This knowledge area provides information about a variety of disciplines closely related to software engineering. These include: Computer Engineering, Computer Science, Management, Mathematics, Project Management, Quality Management, Software Ergonomics, and Systems Engineering. Each of these disciplines is described in brief, and summarize the Body of Knowledge for each field, if it has one. This is accomplished through a simple bullet point list, with refences to external documents mentioned where appropriate..

  • Testing in the Software Development Life Cycle and Its Importance
    International Journal of Engineering and Information Systems (IJEAIS) ISSN: 2643-640X Vol. 3 Issue 9, September – 2019, Pages: 15-20 Testing in the Software Development Life Cycle and its Importance Noortaj Department of Computing and Technology Abasyn University Peshawar, Pakistan Email: [email protected] Abstract : Software development life cycle is a structure followed by the development team within the software organization imposed on the development of software product. The important role of testing in the software development life cycle is to improve the performance, reliability, and quality of the software. I believe testing should be thoroughly planned and conducted throughout the Software development life cycle for best results. Hence, software testing is facing different challenges. In this article, i have explained different phases of the software development life cycle, different testing techniques and its importance. Keywords: Software Development Life Cycle Testing, Testing in the Software Development Process, Software Testing, Importance of testing. 1. INTRODUCTION Testing plays an important role in the software development life-cycle to recognize the defects in the development process and resolve those defects. But before the explanation of the Software development life cycle, I would like to explain the phases of the software development process. Phase 1 Requirement collection and Analysis: For the collection of requirements a discussion is conducted to analyze the requirements and to state how the problem should be solved. The main work of the requirement collection is to determine the anticipated issues and it helps companies to finalize the necessary timeline in order to complete the work of that system in time.

  • Definition of Software Construction Artefacts for Software Construction
    Chapter 3: Internet and Applications Definition of Software Construction Artefacts for Software Construction M.Zinn, G.Turetschek and A.D.Phippen Centre for Information Security and Network Research, University of Plymouth, Plymouth United Kingdom e-mail: [email protected]; [email protected], [email protected] Abstract The definition of a service based software construction process, published in 2007 (Zinn, 2007), builds on the use of software construction artefacts (SCA). These artefacts form useable building blocks (units of modelling) for software, which can be implemented in a software product by a service. The building blocks are categorized in four different types (GUI, data, function and structure). The foundation for the use of these artefacts is the method of the software construction process which constructs the software similar to the methods used in computer aided design (CAD). This paper refines and expands on the definition of the artefacts to present the current state of research in software construction procedures. It will show how the artefacts are constructed and how they can be used in software construction. In addition the software construction artefacts will be compared to components, modules and objects. Based on this definition of the application area, further potential scenarios for the use of the artefacts, as well as their properties and points still being worked on, are shown. The purpose is to create a more exact description, definition of the software construction artefacts to obtain a better understanding of the software construction process. Keywords Computer Aided Design (CAD), software construction process (SCP), software engineering, (web) services, software construction artefacts (SCA) and software construction services (SCS), model driven development (MDD) 1.

  • A Survey of System Development Process Models
    Models for Action: Developing Practical Approaches to Electronic Records Management and Preservation Center for Technology in Government State Archives and Records Administration A Survey of System Development Process Models Introduction This document provides an overview of the more common system development Process Models, used to guide the analysis, design, development, and maintenance of information systems. There are many different methods and techniques used to direct the life cycle of a software development project and most real-world models are customized adaptations of the generic models. While each is designed for a specific purpose or reason, most have similar goals and share many common tasks. This paper will explore the similarities and differences among these various models and will also discuss how different approaches are chosen and combined to address practical situations. Typical Tasks in the Development Process Life Cycle Professional system developers and the customers they serve share a common goal of building information systems that effectively support business process objectives. In order to ensure that cost-effective, quality systems are developed which address an organization’s business needs, developers employ some kind of system development Process Model to direct the project’s life cycle. Typical activities performed include the following:1 · System conceptualization · System requirements and benefits analysis · Project adoption and project scoping · System design · Specification of software requirements · Architectural design · Detailed design · Unit development · Software integration & testing · System integration & testing · Installation at site · Site testing and acceptance · Training and documentation · Implementation · Maintenance 1 Kal Toth, Intellitech Consulting Inc. and Simon Fraser University; list is partially created from lecture notes: Software Engineering Best Practices, 1997.

In this report I describe the research I have conducted during my internship at Operations and IT Banking ING (OIB ING) which is the final facet of my MSc education in Systems Engineering, Policy Analysis and Management at the faculty of Technology, Policy and Management (TPM), Delft University of Technology. Performing this research and writing this Thesis was, at some periods, a struggle and intellectual challenge. However, most of the times, I felt delighted of the work that I did and the contribution it will finally make. For this research, I could not have wished for a better environment to perform in. The department in which I was stationed (Solution Delivery Centre Call Face NL) was very comfortable as a research setting. I experienced its employees as flexible, interested and most of all very helpful. The most difficult aspect of this graduation project was to conduct it individually. In the entire MSc education programme, every project consisted of multiple project members.

  • Lean Thinking in Software Engineering : a Systematic Review
    International Journal of Software Engineering & Applications (IJSEA), Vol.8, No.3, May 2017 LEAN THINKING IN SOFTWARE ENGINEERING : A SYSTEMATIC REVIEW Fernando Sambinelli 1and Marcos Augusto Francisco Borges 2 1Federal Institute of Education, Science and Technology of São Paulo, Hortolândia, Brazil 2School of Technology, University of Campinas, Limeira, Brazil ABSTRACT The field of Software Engineering has suffered considerable transformation in the last decades due to the influence of the philosophy of Lean Thinking. The purpose of this systematic review is to identify practices and approaches proposed by researchers in this area in the last 5 years, who have worked under the influence of this thinking. The search strategy brought together 549 studies, 80 of which were classified as relevant for synthesis in this review. Seventeen tools of Lean Thinking adapted to Software Engineering were catalogued, as well as 35 practices created for the development of software that has been influenced by this philosophy. The study provides a roadmap of results with the current state of the art and the identification of gaps pointing to opportunities for further research. KEYWORDS Lean Thinking, Lean IT, Agile, Software Engineering, Software Development, Systematic Review 1. INTRODUCTION Lean has been studied by researchers for almost half a century [1]. Publications in this field have increased considerably with an increasing number of industries trying to adopt this philosophy of work in its productive processes[2]. The term Lean emerged in the early 1980s when a quality gap was observed between Western and Japanese products, being most clearly noticed in the car manufacturing industry. The most comprehensive research on the differential features of Japanese productive methods was conducted by the International Motor Vehicle Program (IMVP) at the Massachusetts Institute of Technology (MIT) [3].
